Norbert Weissman was Paulina Marcovici's brother. Norbert lived in Bucharest or Piatra Neamt (photo from July, 1910 taken in Piatra Neamt). Top right photo of Norbert and unknown woman presumed to be Norbert's spouse. Bottom right photo of Paulina's siblings: Norbert, Speranza and Oscar.

I understand from my Israeli cousin that Norbert studied engineering in Germany, where he married. Norbert then returned to Romania where he owned a hardware store.
